Yes, as explained by Judge Jonathan Goodman in Procaps S.A. v. Patheon, Case No. 12-24356 (S.D. Fla. Apr. 24, 2015), Federal Rule of Evidence 706 expressly permits such depositions.
In the case (also detailed in a prior post), Judge Goodman appointed a neutral computer forensic firm and a special master to assist with e-discovery issues after plaintiff Procaps S.A. failed to institute a litigation hold for more than a year after filing suit and after allegations of evidence spoliation arose. The computer forensic firm determined Procaps deleted nearly 200,000 files of which approximately 5,700 contained relevant search terms. Patheon then moved to depose the forensic firm, which the judge allowed not only because Evidence Rule 706 permitted it, but also because it would assist the court to better understand the various e-discovery issues presented in the case.
Evidence Rule 706 permits federal courts to appoint expert witnesses on its own or at the request of a party and states that the expert:
- must advise the parties of any findings the expert makes;
- may be deposed by any party;
- may be called to testify by the court or any party; and
- may be cross-examined by any party, including the party that called the expert.
Judge Goodman noted that “plung[ing] into the thicket of the details surrounding Procaps ESI” would be “daunting” without testimony from the forensic firm that analyzed it. As a result, he permitted the deposition for several reasons: 1) The report was thousands of pages; 2) the computer forensics firm had been involved in the case for over a year; 2) the special master, and not the judge, was privy to e-discovery developments; and 4) any issues regarding ESI spoliation would be fact intensive and based in part on the findings of the appointed expert.
